Copd (Definition)

COPD may include chronic bronchitis, emphysema, or both. Chronic bronchitis is the production of increased mucus caused by inflammation. Bronchitis is considered chronic if you cough and produce excess mucus most days for three months in a year, two years in a row. Emphysema is a disease that damages the air sacs and/or the smallest breathing tubes in the lungs. ...Read more

Spirometry results essentially normal spirometry. Hyperinflation questionable the single breath diffusing capacity is moderately impaired. COPD?

Spirometry results essentially normal spirometry. Hyperinflation questionable   the single breath diffusing capacity is moderately impaired. COPD?

Possible: A reduced DLCO/Va points to damage or scarring in the lung tissue and emphysema (especially if you have been a smoker) or other interstitial lung diseases may be the cause. The normal lung function however is not compatible with COPD but then I don't understand what you meant by hyperinflation in the presence of normal lung function test. See a pulmonologist. ...Read more

Why would patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Why would patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Low blood oxygen: At the advanced stages of copd, the lungs do not perform their function well, oxygen has a harder time crossing into the blood stream. At this point, the body is not getting enough energy, the blood oxygen level is low. Raising the amount of inhaled oxygen offsets the problem, and prolongs life. Oxygen is used at the lowest amount that would achieve the goal. ...Read more

Why oxygen supplementation contraindicated with obstructive lung disease?

Why oxygen supplementation contraindicated with obstructive lung disease?

Not usually: COPD is a problem with the ability of the lungs to expel air, which causes poor oxygenation. People with COPD are often treated with oxygen; however, if supplemental oxygen levels are too high it can cut off a person's ability to trigger their own breathing mechanism. If the disease is severe you actually may not be able to survive without the use of oxygen. ...Read more

Copd ---- what's considered a high concentration of required oxygen?

Copd ---- what's considered a high concentration of required oxygen?

Delivery: Perspective is that 21% is the concentration from the air we breath. 2-3% increase in concentration is from each liter of oxygen added. So 1 liter is about 24% and this can go through a nasal canula tube. Over 4-5 liters, you cannot get this from a canula and need continuous flow to maintain the concentration. This would be considered "high" in my book. Not sure if this answers your question. ...Read more

Can steady exposure to carbon monoxide cause respiratory problems like emphysema, copd, asthma?

Can steady exposure to carbon monoxide cause respiratory problems like emphysema, copd, asthma?

Would never happen: Carbon monoxide has strong affinity to the hemoglobin and its diffusibility through membrane is high. Before any other condition like asthma, COPD can occur from it, a person is dead. There will be no study to prove that. ...Read more

Does being dehydrated affect lung capacity?

Does being dehydrated affect lung capacity?

Not direclty: Being dehydrated would not affect lung capacity in terms of spirometric testing, however,it will cause weakness similar to that due to limitation of lung capacity. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

What is the capacity of asthmatic lungs vs non asthmatic lungs?

What is the capacity of asthmatic lungs vs non asthmatic lungs?

Lung capacity/asthma: Total lung capacity is the volume of air in the lungs at the end of maximal inspiration. Asthmatics can have higher lung volumes than normal people because their lungs become hyperinflated when they have attacks. They have trouble breathing all the way out, so the volume left over afterward, the residual lung volume, is also elevated. In severe asthmatics, fibrosis/scars can decrease volumes. ...Read more

Why do you not give more than 2l/min of oxygen to a client with copd?

Why do you not give more than 2l/min of oxygen to a client with copd?

Not true: The comment is a fallacy. A patient who has COPD and needs oxygen should get as much liter flow to keep a sat>88. Patients with high co2 buildup should use oxygen to a saturation of>86-87. That is because that pts co2 will rise if increased oxygen is given, making the pt less alert. ...Read more

Can I simply just turn up my oxygen if I have COPD and fly regularly on commercial flights?

May be ok: Many times, i will tell my patients with COPD and oxygen to turn up their oxygen level slightly when flying on a plane. Most of the time, that can do the trick. If available, i would see if you can do an actual flight simulation, where they have you breathe lower level of oxygen to see what happens to your oxygen level. ...Read more

I have copd. What can cause me to have a great oxygen level when lying still, but have it go down when active? More active i am, the lower it goes.

Activity: In some patients with copd, the lungs can't supply enough oxygen to keep the oxygen level (saturation) normal. This may happen with activity when the body starts to use up its oxygen supply. If you rest, you can catch up and get back to normal. However, you may need oxygen at this point. There are specific criteria to qualify, so talk to your family doctor or lung specialist. ...Read more

Most people with copd, have a higher oxygen level when sitting. Why is mine 95-96 when sitting an gets up to 97-98 when active. Theirs gets lower .

COPD O2 saturation: COPD patients not a uniform group Those with a decreased number of operational blood vessels in the lung will decrease the O2 saturation when they move because they have less O2 to give to the body tissues and the deceased sat.reflects this. You are in a group that does not have this problem. Your Sat.is up because you take deeper breaths when you move and bring in blood vessels not used at rest. ...Read more

What is considered a normal oxygen saturation for a person with COPD and why is it considered normal?

What is considered a normal oxygen saturation for a person with COPD and why is it considered normal?

Anything above 90%: > or equal to 90% is normal. This is related to the hemoglobin oxygen dissociation curve. There is a certain percentage of oxygen saturation before your cells will not let oxygen leave cell and go to tissue. That is somewhere around 88-92% so since the sensors are good only 90% + or - 2% points, we use 90%. ...Read more

I have copd, but why am i still short of breath while on oxygen?

I have copd, but why am i still short of breath while on oxygen?

Complicated dyspnea: Shortness of breath relates to the work of breathing as well as oxygenation. COPD when severe enough to need oxygen likely is associated with significant increase in the work of moving air into and out of the lungs. If still short of breath on oxygen there may still low oxygen in the blood stream or the work of getting enough into the blood stream may be causing the shortness of breath. ...Read more

Is a 70  year old woman with mild COPD and asthsma  likely to need oxygen full time in the near future?

Not Necessarily : Asthma is reversible . COPD is not reversible. Most pts requiring oxygen is because they have chronic hypoxemia. It is common for COPD to turn into chronic hypoxemia requiring constant oxygen but much less for asthmatic pts unless they are in constant "status asmarhicus" or develope cor pulmonale with cardiac insufficiency. ...Read more
